high-power amplifier, and antenna. For a transmitter, the signal is generated by the source. The mixer changes the frequency of the signal. The filter removes undesired frequencies. The amplifier increases the signal. The antenna transforms the electrical current into a radio wave. The other amplifier provides the electrical signal. It also feeds into the mixer. For a receiver: This diagram shows a conceptual layout of a typical receiver. Included in it are seven elements. They are, in order: antenna

How to choose the Best Electrical Contractor Selecting a qualified and competent electrician for your home or business can be an uphill task. This can be even more challenging especially if you don’t know exactly what you want. This is so because you know that there’s a problem but you don’t have the particular know-how to establish the source of the problem. There are specific traits that one should look at when choosing an electrical contractor. First, an electrical contractor should have valid

Despite developing a way to produce free electricity for the world, the genius was ignored, or his ideas stolen from him. He was celibate his entire life, claiming he didn’t want any distractions from his work. He created alternating current which, in comparison to direct current, uses thinner wires, has a higher voltage capacity, and a longer transmitting distance. He conceptualized Radar in 1917; years before Robert A. Watt developed it in 1938. He created a hydroelectric plant in Niagra Falls, discovered

relationship between voltage, current, and resistance. Go to ⎝Battery-Resistor Circuit. Click on the green “Run Now” button. The simulation should look like the picture to the right. 1. Change the resistance and voltage. Observe what happens to the current. Note the relationship you observed between each of the following: (direct, inverse, none) a. resistance and current = _indirect_______________________ b. voltage and current = direct__________________________

property of a substance which makes it oppose the flow of an electric current through it. Generally, metals acids and liquid salts and salt solutions are very good conductors of electricity. Metals with higher numbers of delocalized electrons have higher conductivities than those with fewer delocalized electrons. For example, aluminium is more conductive than copper which is also more conductive than copper. When an electric current is applied to a conductor, the delocalized electrons assume a directed

Check “show battery” and “show cores”, watch what happens, adjust some variables 1. Why do electrons (blue dots) move? The flow of current (+) is opposite to the flow of the electrons. ; note if toward or away from + terminal of the battery. The electrons move because they are being attracted towards the positive side of the battery and thus move because of the attraction in the battery. 2. What does the Ammeter (on the left) measure? How is this shown in the sim? It measures the rate
